Week 5 of the men’s study on 1 Corinthians, focusing on what the letter teaches about discipleship; the theme for the week: “A disciple takes sin seriously.”
Paul’s words in 1 Corinthians 5 confront a church that had grown comfortable with open, unrepentant sin.
The study leader–admitting he is “not a seminary guy,” but a fellow learner who tends to come at hard topics head-on–walked the group through the passage to show that genuine disciples grieve over sin, deal with it for the good of the sinner and the body, and anchor their hope in Christ, the Passover Lamb who was sacrificed for us.
One big idea: taking sin seriously is essential to following Jesus because the cross proves just how serious God already is about it.
Key Points / Exposition
1. We Soften Sin with Softer Words
Group brainstorm of the euphemisms we reach for: “struggle, mistake, weakness, bad habit, failure, I had a bad night, everyone’s doing it.”
Soft language can move us from fighting sin to explaining it away.
Question posed: “Is the issue how ugly my sin looks next to someone else’s, or whether God calls it sin?”
2. The Presenting Issue at Corinth (1 Corinthians 5:1-2)
Ongoing sexual relationship: “a man is sleeping with his father’s wife”–most likely his step-mother.
Shock factor: “Even pagans don’t tolerate this.”
Paul’s deeper concern: the church was proud instead of grieving.
Key diagnostic: the first response to sin should be mourning, not outrage.
Outrage often puts us above a sinner; grief reflects God’s heart.
3. Why the Whole Church Is Responsible (vv. 3-5)
Church discipline is a family matter: believers are “one body.”
“Hand this man over to Satan” = remove him from the protective fellowship of the church so that he might wake up, repent, and be saved.
Discipline goal: restoration, never revenge or humiliation–the ultimate purpose is “that his spirit may be saved on the day of the Lord.”
Confronting sin is loving when it points to repentance and offers help; it turns unloving when it’s either self-righteous accusation or apathetic tolerance.
4. Tolerance Becomes Infection (vv. 6-8)
Yeast picture: “Don’t you know that a little yeast leavens the whole batch of dough?” A small amount permeates the whole loaf.
Tolerated sin lowers the holiness bar, emboldens new compromises, erodes trust, and teaches younger believers that the church doesn’t mean what it says–it silently “moves the line” for the entire congregation.
Illustration: the VMI honor code–one cadet’s cheating dishonors the whole corps; violations mean expulsion because reputation and mission are at stake.
5. The Cross Proves How Seriously God Takes Sin (v. 7)
“Christ, our Passover Lamb, has been sacrificed”–His blood shields believers from judgment and sets them free to live as God’s redeemed people.
James 2:10–whoever stumbles at one point is guilty of breaking the whole law, showing everyone’s need for Christ.
God’s answer wasn’t tolerance but substitution: His Son died a brutal death to free us.
Therefore, disciples refuse to make peace with the very thing Jesus died to defeat.
6. Discipleship Rhythm: Confession and Repentance
Psalm 139:23-24–invite God to search and expose hidden sin, and to lead in the everlasting way.
1 John 1:9–God is faithful and just to forgive confessed sin and purify us from all unrighteousness.
James 5:16–confess to trusted brothers and pray for healing; the prayer of a righteous person is “powerful and effective.”
Application: cultivate relationships where honest confession is normal and restoration is pursued.
Major Lessons & Revelations
Softening vocabulary never softens sin’s reality before God.
Grieving over sin is the first sign a disciple is taking it seriously.
Loving confrontation seeks a brother’s restoration, not his humiliation.
Unchecked sin spreads through a church like yeast through dough.
The cross is both the measure of sin’s seriousness and the source of our hope for forgiveness.
Regular confession and repentance keep a disciple sensitive to God and to others.
Believers are to judge those inside the church, leaving those outside to God’s judgment (1 Corinthians 5:12-13).
Comparing your sin to someone else’s is dangerous: it downplays personal guilt, breeds self-righteousness, and ignores God’s absolute standard.
Practical Application
Ask God to search your heart and name any offensive way.
Call sin “sin” in your own life–no euphemisms, no excuses.
If you are caught in habitual, unrepentant sin, seek a trusted brother today and invite accountability: schedule regular check-ins, agree on honesty and prayer support, and review progress together.
When you learn of a brother’s sin, respond first with grief, then with loving, gospel-rooted confrontation aimed at restoration.
“Remove old yeast”: identify one recurring compromise, confess it, set a boundary (filter, schedule change, accountability), and replace it with a Christ-honoring habit.
Guard the health of the church by refusing to tolerate what Christ died to remove.
Conclusion & Call to Response
Discipleship is not a quest to appear perfect but a commitment to stay honest before God and one another.
Because Jesus is our Passover Lamb, sin can be faced head-on, mourned, confessed, and forsaken–never renamed or ignored.
The goal of any discipline or confession is always the same: a brother restored and a church purified for the glory of Christ.
Insights
Comfort will rename your chains “little habits” until they own you; dare to call sin sin.
Outrage makes me feel superior; grief leads me to repentance, because humility heals faster.
A hidden compromise today becomes tomorrow’s culture; guard your heart before yeast spreads everywhere.
Jesus didn’t endure the cross so you could flirt with darkness; He died to free you fully.
Love isn’t passive tolerance; it’s a brave conversation that says, “I won’t let you settle for less.”
One unconfessed habit can cost a community its credibility; holiness is our shared pursuit.
Stop comparing your mess to someone else’s disaster; the only standard is what God says.
